中文摘要 | this paper describes an attractive method to make biodiesel from soybean soapstock (ss). a novel recovery technology of acid oil (ao) from ss has been developed with only sulfuric acid solution under the ambient temperature (25 +/- 2 degrees c). after drying, ao contained 50.0% ffa, 15.5% tag 6.9% dag 3.1% mag 0.8% water and other inert materials. the recovery yield of ao was about 97% (w/w) based on the total fatty acids of the ss. the acid oil could be directly converted into biodiesel at 95 degrees c in a pressurized reactor within 5 hours. optimal esterification conditions were determined to be a weight ratio of 1 : 1.5 : 0.1 of ao/methanol/sulfuric acid. higher reaction temperature helps to shorten the reaction time and requires less catalyst and methanol. ester content of the biodiesel derived from ao through one-step acid catalyzed reaction is around 92%. after distillation, the purity of the biodiesel produced from ao is 97.6% which meets the biodiesel specification of korea. the yield of purified biodiesel was 94% (w/w) based on the total fatty acids of the soapstock. |
